The method uses the principle of enzyme-linked immunosorbent assay to determine the permethrin and related pyrethroids. The test sample was coated with magnetic particles coated with a pyrethroid-specific antibody and added to a disposable test tube for 20 minutes. A synthetic pyrethrin conjugate is then added. The synthetic pyrethroid and pyrethroidase conjugates in the sample compete with each other for the antibody binding site on the magnetic particles. Incubate for 30 minutes, in which the magnetic field is applied to the paramagnetic particles in the fixed test tube (referring to the magnetic particles combined with the pyrethroid and the enzyme-labeled permethrin complex, which are proportional to their initial concentrations), while allowing no The combined reagent is disposed of. The particles are washed with a washing solution after the reagents which have not reacted are discarded. Synthetic pyrethroids can be detected by the addition of an enzyme substrate (hydrogen peroxide) and a color developer (TMB).
Ice bucket is mainly used as a container for beer, and it is suitable for various bar parties, family picnics and gardens. The main material is galvanized iron and tinplate, and the thickness of the barrel is 0.28mm and 0.35 mm.
As for the size ,color logo and the handle type of our high quality bucket, it will be customized according to the different needs of customers.
And our bar buckets are relatively cheap, durable and easy to use. we will pay more attention to details, develop and innovate with advanced manufacturing technology.
